Is this something we could use in Linux Mint for improving internet security?The build process is a bit over my head. That said it doesn't look that difficult. Just some things in the instructions that aren't familiar to me.I use OpenDNS on my home network.

Perhaps you can use what is already included in the Linux Mint install or add a DNS Proxy via the Linux Mint Synaptic Package Manager or Terminal:

dnsproxy

Found in the Linux Mint Synaptic Package Manager:

dnsproxy forwards DNS queries to two previously configured nameservers:one for authoritative queries and another for recursive queries.The received answers are sent back to the client unchanged.No local caching is done.

Primary motivation for this project was the need to replace Bind servers withdjbdns in an ISP environment. These servers get recursive queries fromcustomers and authoritative queries from outside at the same IP address.Now it is possible to run dnscache and tinydns on the same machine withqueries dispatched by dnsproxy.

Another possible scenario is a firewall where proxy queries should beforwarded to the real server in a DMZ.

dnsmasq

Linux Mint Pre-installs dnsmasq-base (found at least on Mint 11 standard) which is curious as it contains the dnsmasq executable and documentation but NOT the infrastructure required to run it as a system daemon. For that, the Linux Mint user must also use the Synaptic Package Manger or Terminal to install the dnsmasq package.
